Hello,
I have got a problem with my W-LAN-card and it's interrupt-address. Can someone help me?
Thanks, Andreas
Symptoms: Sound-Card is running under Linux. I can install the Wireless-LAN Card, YAST2 won't show errors, but it wouldn't work, if I do so. Both cards are running on IRQ 11, if I set the Wireless-LAN card to active. Then sometimes the W-LAN card works, then sound listens bad (a waving, ...) or sound listens well but the W-LAN card didn't work. Interesting: Under Windows XP Home Edition the sound-card is running on IRQ 10, the W-LAN card on IRQ 11. Both are working very well.
Then I booted with pci-noacpi in the boot string and both cards are running now. But they are not running very well:
You almost ALWAYS need pci=acpi in any laptop to get all the devices working. Your symptoms are classic for a non-working acpi. Acpi is needed to route interrupts in many laptops (as well as other machines) which share interrupts.
So turning acpi off was the wrong thing to do in 95% of the cases involving laptops. You must check your bios to make sure it does not have a setting that disables acpi.
Acpi and apm are mutually exclusive, so don't start apm.
There is a field "Setup by OS", that is unchecked. AND: there is no field with apm or acpi. This bios is very silly, I think - you can set nothing you need. Is it possible, that acpi isn't running, instead of I had started with pci=acpi? AND: both cards are running. But they interfere with each other and disturb each other. So the sound-card is playing signals of the Wireless-LAN card and if I use the Wireless-LAN card, Internet-Sites would be loaded sooooo slowly - there is a modem faster. (and I'm using DSL) Any Answer? Andreas
